* USB: serial: fix missing locking on fifo in write callbackJohan Hovold2010-05-20
| | | | | | | | | | | | On errors the fifo was reset without any locking. This could race with write which do kfifo_put and perhaps also chars_in_buffer and write_room. Every other access to the fifo is protected using the port lock so better add it to the error path as well.

* USB: serial: fix generic chars_in_bufferJohan Hovold2010-05-20
| | | | | | | | | | | | Make sure chars_in_buffer accounts also for data in host stack queues. This fixes the problem with tty_wait_until_sent returning too soon at close which could cause the final write urb to be cancelled.

* USB: pl2303: increase bulk-in buffer size to 256 byteJohan Hovold2010-05-20

| | | | | | | | | | | | | | | | Increase the bulk-out buffer size from 64 to 256 byte. This gives a significant increase in throughput already at 1Mbaud as well as lowered CPU usage. The buffer is big enough to keep up also at 3Mbaud (128b would not suffice). 64b 256b 921k: 640 KB/s 870 KB/s 3M: 640 KB/s 2520 KB/s Signed-off-by: Johan Hovold <jhovold@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

* USB: serial: allow drivers to define bulk buffer sizesJohan Hovold2010-05-20
| | | | | | | | | | | | | | Allow drivers to define custom bulk in/out buffer sizes in struct usb_serial_driver. If not set, fall back to the default buffer size which matches the endpoint size. Three drivers are currently freeing the pre-allocated buffers and allocating larger ones to achieve this at port probe (ftdi_sio) or even at port open (ipaq and iuu_phoenix), which needless to say is suboptimal.

* usb-console: pass baud from console to the initial tty openJason Wessel2010-05-20
| | | | | | | | | | | | | | | | | The usb console code has had a long standing problem of not being able to pass the baud rate from the kernel argument console=ttyUSB0,BAUD down to the initial tty open, unless you were willing to settle for 9600 baud. The solution is to directly use tty_init_termios() in usb_console_setup() as this will preserve any changes to the initial termios setting on future opens.

* include cleanup: Update gfp.h and slab.h includes to prepare for breaking ↵Tejun Heo2010-03-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | implicit slab.h inclusion from percpu.h percpu.h is included by sched.h and module.h and thus ends up being included when building most .c files. percpu.h includes slab.h which in turn includes gfp.h making everything defined by the two files universally available and complicating inclusion dependencies. percpu.h -> slab.h dependency is about to be removed. Prepare for this change by updating users of gfp and slab facilities include those headers directly instead of assuming availability. As this conversion needs to touch large number of source files, the following script is used as the basis of conversion. http://userweb.kernel.org/~tj/misc/slabh-sweep.py The script does the followings. * Scan files for gfp and slab usages and update includes such that only the necessary includes are there. ie. if only gfp is used, gfp.h, if slab is used, slab.h. * When the script inserts a new include, it looks at the include blocks and try to put the new include such that its order conforms to its surrounding. It's put in the include block which contains core kernel includes, in the same order that the rest are ordered - alphabetical, Christmas tree, rev-Xmas-tree or at the end if there doesn't seem to be any matching order. * If the script can't find a place to put a new include (mostly because the file doesn't have fitting include block), it prints out an error message indicating which .h file needs to be added to the file. The conversion was done in the following steps. 1. The initial automatic conversion of all .c files updated slightly over 4000 files, deleting around 700 includes and adding ~480 gfp.h and ~3000 slab.h inclusions. The script emitted errors for ~400 files. 2. Each error was manually checked. Some didn't need the inclusion, some needed manual addition while adding it to implementation .h or embedding .c file was more appropriate for others. This step added inclusions to around 150 files. 3. The script was run again and the output was compared to the edits from #2 to make sure no file was left behind. 4. Several build tests were done and a couple of problems were fixed. e.g. lib/decompress_*.c used malloc/free() wrappers around slab APIs requiring slab.h to be added manually. 5. The script was run on all .h files but without automatically editing them as sprinkling gfp.h and slab.h inclusions around .h files could easily lead to inclusion dependency hell. Most gfp.h inclusion directives were ignored as stuff from gfp.h was usually wildly available and often used in preprocessor macros. Each slab.h inclusion directive was examined and added manually as necessary. 6. percpu.h was updated not to include slab.h. 7. Build test were done on the following configurations and failures were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my distributed build env didn't work with gcov compiles) and a few more options had to be turned off depending on archs to make things build (like ipr on powerpc/64 which failed due to missing writeq). * x86 and x86_64 UP and SMP allmodconfig and a custom test config. * powerpc and powerpc64 SMP allmodconfig * sparc and sparc64 SMP allmodconfig * ia64 SMP allmodconfig * s390 SMP allmodconfig * alpha SMP allmodconfig * um on x86_64 SMP allmodconfig 8. percpu.h modifications were reverted so that it could be applied as a separate patch and serve as bisection point. Given the fact that I had only a couple of failures from tests on step 6, I'm fairly confident about the coverage of this conversion patch. If there is a breakage, it's likely to be something in one of the arch headers which should be easily discoverable easily on most builds of the specific arch.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit e1108a63e10d344284011cccc06328b2cd3e5da3 ("usb_serial: Use the shutdown() operation") breaks the ability to use a usb console starting in 2.6.33. This was observed when using console=ttyUSB0,115200 as a boot argument with an FTDI device. The error is: ftdi_sio ttyUSB0: ftdi_submit_read_urb - failed submitting read urb, error -22 The handling of the ASYNCB_INITIALIZED changed in 2.6.32 such that in tty_port_shutdown() it always clears the flag if it is set. The fix is to add a variable to the tty_port struct to indicate when the tty port is a console.

| * | USB: remove references to port->port.count from the serial driversAlan Stern2010-03-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch (as1344) removes references to port->port.count from the USB serial drivers. Now that serial ports are properly reference counted, port.count checking is unnecessary and incorrect. Drivers should assume that the port is in use from the time the open method runs until the close method is called.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We have lots of callers that do not need to do this in the first place. Remove the calls as they both cost CPU and for big buffers can mess up the multi-page allocation avoidance.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This driver has its own (surplus) backup queue system which wants removing from the receive overflow logic. Do this at the same time as removing the request_room logic Signed-off-by: Alan Cox <alan@linux.intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
